Zamioculcas plant named ‘EDZAM1701’

ABSTRACT

‘EDZAM1701’ is a new and distinctive  Zamioculcas  plant which is characterized by a very upright growth habit, with an abundance of leaves comprised of light green and glossy leaflets born on long very light green petioles. The new plant propagates successfully by leaf cuttings and has shown to be uniform and stable in the resulting generations from asexual propagation.

Latin name of the genus and species: The Latin name of the genus andspecies of the novel variety disclosed herein is Zamioculcas zamiifolia(hort. Lodd.) Engl.

Variety denomination: The inventive variety of Zamioculcas disclosedherein has been given the variety denomination ‘EDZAM1701’.

BACKGROUND OF THE INVENTION

Parentage: ‘EDZAM1701’ is a seedling selection resulting from thecontrolled pollination of a first unnamed and unpatented Zamioculcaszamiifolia plant, the seed parent, with a second unnamed and unpatentedZamioculcas zamiifolia plant, the pollen parent, at a commercial nurseryin Maasdijk, The Netherlands, in the summer of 2014. In the summer of2015, one plant was observed to exhibit unique growth characteristicsand was isolated for further evaluation in order to confirm thedistinctness and stability of the characteristics first observed. Uponconfirmation of distinctness and stability, ‘EDZAM1701’ was selected forcommercialization.

Asexual Reproduction: Asexual reproduction of ‘EDZAM1701’ was firstaccomplished in May of 2016 by way of stem cuttings at a commercialgreenhouse in Maasdijk, The Netherlands. Four successive generationsproduced from stem cuttings have shown that the unique features of theinstant cultivar are stable and reproduce true to type.

SUMMARY OF THE INVENTION

The cultivar ‘EDZAM1701’ has not been observed under all possibleenvironmental conditions and the phenotype may vary somewhat withvariations in the instant environment such as temperature, day length,and light intensity, without, however, any variance in genotype. Thefollowing characteristics have been repeatedly observed and representthe distinguishing characteristics of the new Zamioculcas plant,‘EDZAM1701’. These traits, in combination, distinguish ‘EDZAM1701’ as anew and distinct cultivar.

-   -   1. Zamioculcas ‘EDZAM1701’ exhibits a very upright growth habit;        and    -   2. Zamioculcas ‘EDZAM1701’ exhibits an abundance of foliage; and    -   3. Zamioculcas ‘EDZAM1701’ exhibits light green leaflets borne        on very light green petioles.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinctvariety of Zamioculcas zamiifolia known as ‘EDZAM1701’, based uponobservations of 12 month-old plants, potted into 15 cm nursery pots andgrown indoors at a commercial nursery in Maasdijk, The Netherlands.Plants were grown in full sun using accepted fertility and irrigationpractices for Zamioculcas plants. With the exception of preventativefungicides, no chemical pest control measures were employed.Furthermore, no artificial light or photoperiodic treatments were givento the plants. Observation data was recorded in October of 2019.

Those skilled in the art will appreciate that certain characteristicswill vary with older or, conversely, with younger plants. ‘EDZAM1701’has not been observed under all possible environmental conditions. Wheredimensions, sizes, colors and other characteristics are given, it is tobe understood that such measurements are approximations or averages setforth as accurately as practicable. The phenotype of the variety maydiffer from the descriptions set forth herein with variations inenvironmental, climactic and cultural conditions. Color notations arebased on The Royal Horticultural Society Colour Chart, The RoyalHorticultural Society, London, sixth edition, 2015.

A botanical description of ‘EDZAM1701’ and comparisons with the parentplants and the most similar variety of common knowledge are providedbelow.
